This invention is an improvement in racks for supporting articles to be electro-plated, and more particularly in means to support relatively long articles in a favorable position to receive the deposit.

Since the article to be plated is a part of the circuit, there must be a good electrical connectionbetween it and the rack, from which the negative lead of the circuit extends,

In certain ware, such for instance, as the brace arms of automobile tops, a firm grip and close contact between the article and the rack is somewhat diificult to obtain.

Articles of this character have an opening at each end, and it is desirable that the supporting elements of the rack engage within the openings to leave the exterior of the article wholly exposed for the deposit.

One of the primary objects of the present invention is the provision of a type of rack or hanger, especially adapted for su ort ing ware of this character, wherein the engaging elements of the rack or hanger are so the ends of the article, and to depress resiliently into contact with the article, whereby to insure good conduction. I

With these and other objects in View the invention. consists in the construction and novel combination,of parts fully described hereinafter, illustrated in the accompanying drawings, and pointed out in the claims appended hereto, it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims, may be resorted to without departing from the spirit of the invention. A

In the drawings forming a part hereof Fig. 1 is a transverse vertical section of a tank provided with the improved tank or hanger. V

Fig. 2 is a detail in perspective of a part of the rack. f

The present embodiment of the invention is shown in connectionwith a plating tank 1 ofcusual construction, having a plurality of cross bars 2 extending either transversely or longitudinallyof the tank, and resting at arranged as to engage within the openings attheir ends upon the walls of the tank. The bars 2 are of conducting material, and the negative leadof the circuit is connected to said bars. The elements of the rack proper to be1 described, are also of conducting materia,

lhe improved rack comprisesa substan- Y tially rectangular frame,composed of a bottom member 3, side or end members 4, and a top member 5. Each of the side members 4 extends above the top member 5, and the extended end is provided with a hook 6 for engaging a cross bar 2. As shown in" Fig. '2, these hooks are soarrangedthat the-: rack will hang vrtically from the bar 2, the hook being so constructed that the members 4 of the rack will be directly below the cross bar.

Each of the side membersA is provided with a set of hangers, and the hangers of the sets are in substantial register, so that the article indicated at 7 will be supported horizontally in the tank. Each hanger is composed of wire of suitable gauge, which is doubled upon itself, as shown in Fig. 2, to provide a substantially U-shaped member composed of a body and arms extending alongside each other in spacedrelation. The U-shaped member is then bent to provide portions 8 and 9 extending at substantially a right angle with respect to each other, and the ends of the arms are secured to the side member i by soldering indicated at '10, or otherwise, as may be desired." The end of each arm remote from the body is bent laterally as shown, at 11, and it is these portions of the arms which are connected to the side members.

Each of the hangers is connected to the side member with the portion 8' of the hanger extending upwardly,'and the spacing of the. arms of the hangerat their connection is somewhat greater than the opening of the article with which the hanger'is to engage, In use, the rack is supported as shown in Fig. 1, and the side members 4: are spaced apart from each other so that the openings 0 the article will be in register with the upturned portions 8 of the hangers. The porv 7 mm of the hangers makes a good electrical connection between the hanger and the arms f while leaving the entire external surface 9 the article ex o sed to receive the deposlt. 5 The improved hanger is of particular benefit in plating with chromium.
